Abstract
The utility model provides a dual valve push rod splitting device, which comprises a valve base assembly, a valve body assembly, and a push rod base assembly. The push rod base assembly includes two guide sleeves disposed in a first push rod hole and a second push rod hole respectively; the valve body assembly comprises two spacers which are disposed in a third push rod hole and a fourth push rod hole respectively, a first working opening and a second working opening; and the valve base assembly includes a gas inlet. The dual valve push rod splitting device also comprises two first push rods which are disposed in the two spacers; and two second push rods which are disposed in the two guide sleeves. The dual valve push rod splitting device divides the dual valve push rod into two segments, so that the assembly is easy and the labor hour is saved, the push rod is prevented from blocking even being stuck due to over-high friction force, and the product has longer service life.
Description
Technical field
The utility model relates to a kind of gearbox valve means, is specifically related to a kind of dual valve push rod and divides body device.
Background technique
Along with domestic heavy-duty car recoverable amount maintains sustained and rapid growth; The share that the petroleum resources that highway communication consumed account for national consumption of petroleum total amount constantly rises; The automobile product that offers the low oil consumption of user and possess the good dynamics performance becomes one of main target that present automobile enterprise pursues, and what the power character of automobile and fuel economy were had the greatest impact is the speed ratio and the efficient of speed changer, and speed changer is as can be according to situation conversion velocity ratios such as the engine load and the speed of a motor vehicle; Can make automobile obtain good power character and fuel economy; And reduce engine emission and pollute, adopt the speed changer of more gears to be applied, dual valve is to realize that gearbox just keeps off the key component of conversion; When vehicle is crowded, can improve the Security and the reliability of vehicle driving greatly.
Similar in the market dual valve is as shown in Figure 1, and push rod 1 is that the structure of integral type is set in guide pin bushing 2 and the spacer 3, receive the machining accuracy difference of valve body and tip-lever support endoporus easily and be difficult to the assembling; And in follow-up use, particularly under the automotive environment harsh conditions, push rod receives frictional force excessive and cause clamping stagnation; The stuck valve of push rod is not worked when serious; Cause speed changer high and low shift translation exception, cause the high-grade district of speed changer gear not use, therefore; There is the machining accuracy difference in existing technology and is difficult to assembling, the idle problem of the stuck valve of push rod when serious.
The model utility content
To above-mentioned defective, the purpose of the utility model provides and a kind of the dual valve push rod is divided into two sections branch body device, to solve prior art problems.
For realizing above-mentioned purpose, the technological scheme below the utility model has adopted:
A kind of dual valve push rod divides body device; Comprise valve component, valve component, tip-lever support assembly; Said tip-lever support assembly comprises that two guide pin bushings install respectively in first jogger hole and second jogger hole; Said valve component comprises that two spacers install respectively in the 3rd jogger hole and the 4th jogger hole, one first working hole and one second working hole; Said valve component comprises a suction port, and said dual valve push rod divides body device also to comprise: two first push rods, said two first push rods are arranged in said two spacers; Two second push rods, said two second push rods are arranged in said two guide pin bushings.
Divide body device according to the described dual valve push rod of the utility model embodiment, said first push rod and said second push rod couple.
Owing to adopted above technical characteristics, made the utility model have following advantage and good effect than existing technology:
The first, the dual valve push rod of the utility model divides body device that the dual valve push rod is divided into two sections, and assembling is practiced thrift man-hour easily;
The second, the dual valve push rod of the utility model is can frictional force not excessive and cause clamping stagnation even stuck, and life of product is longer.
Certainly, implement any one specific embodiment of the utility model content, might not have above whole technique effect simultaneously.
Description of drawings
Fig. 1 is an existing technology dual valve schematic representation;
Fig. 2 is a kind of dual valve push rod of the utility model split schematic representation of apparatus;
Fig. 3 is the separately schematic representation that a kind of dual valve push rod of the utility model divides body device.
Embodiment
For ease of understanding, the preferred embodiment of the utility model is done being described in further detail below in conjunction with accompanying drawing.
Please refer to Fig. 2, a kind of dual valve push rod of 3 the utility model split schematic representation of apparatus; It is that screw rod (not shown) valve component 10, valve component 20, tip-lever support assembly 30 usefulness M5 is formed by connecting that a kind of dual valve push rod divides body device; Accomplish gas circuit with valve and exchange and develop in order to realize automobile; Said tip-lever support assembly 30 comprises that two guide pin bushings 31 install respectively in first jogger hole 32 and second jogger hole 33; Said valve component 20 comprises that two spacers 21 install respectively in the 3rd jogger hole 22 and the 4th jogger hole 23, one first working hole 24 and one second working hole 25; Said valve component 10 comprises a suction port 11, and said dual valve push rod divides body device also to comprise: two first push rods 26, said two first push rods 26 are arranged in said two spacers 21; Two second push rods 34; Said two second push rods 34 are arranged in said two guide pin bushings 31, and said first push rod 26 couples with said second push rod 34, because push rod is divided into two; The length of each section is all original for short; It is easier to assemble, and diminished by the influence of the machining accuracy of valve body and tip-lever support endoporus, and service time is longer.
The working procedure of the utility model is following: dual valve is to belong to mechanical valve; Be to control dual valve by the gas control lock valve to accomplish exchange to gas circuit; The initialization state is that gas control lock valve valve rod 40 is pushed down second push rod 34 in second jogger hole 33; Second push rod 34 is unsettled in first jogger hole 32, makes the suction port 11 and first working hole 24 be opening state, and the suction port 11 and second working hole 25 are closed condition; The relief opening 27 and first working hole 24 are closed condition, and the relief opening 27 and second working hole 25 are opening state.It is unsettled to push down in dual valve first jogger hole 32 in second push rod, 34, the second jogger holes 33 second push rod 34 after gas control lock valve valve rod 40 switching-over, and the state between each gas port also exchanges thereupon accordingly, has also just realized the exchange of gas circuit.
Owing to adopted above technical characteristics, made the utility model have following advantage and good effect than existing technology:
The first, the dual valve push rod of the utility model divides body device that the dual valve push rod is divided into two sections, and assembling is practiced thrift man-hour easily;
The second, the dual valve push rod of the utility model is can frictional force not excessive and cause clamping stagnation even stuck, and life of product is longer.
Certainly, implement any one specific embodiment of the utility model content, might not have above whole technique effect simultaneously.
More than disclosed only be the preferred embodiment of the utility model; But be not to be used for limiting itself; Anyly have the knack of those skilled in the art under the situation of the utility model spiritual connotation, the equalization of being done changes and changes, and all should drop in the protection domain of the utility model.
